HOPING YOU WILL BE SATISFIED WITH OUR PRODUCT WE RECOMMEND YOU TO OBSERVE THESE
MAIN PRINCIPLES, IMPORTANT FOR THE SERVICE
LIFE AND PROPER FUNCTIONING OF THE BOILER
1. The installation, lighting of the test fire and training of the operators shall be performed by an
installation company trained by the manufacturer, which shall also fill in the boiler installation record (page 28).
2. When using pellets for heating only use high-quality fuel with the diameter of 6 - 8 mm, made
of soft wood without bark and contaminants (white pellets).
3. During fuel combustion substances are produced that may damage the boiler body. Therefore,
the boiler must be equipped with Laddomat 21 or a thermo-regulation valve to maintain the minimum temperature of return water to the boiler of 65°C.
The operation temperature of the water in the boiler must be in the range of 80-90°C.
4. Each circulation pump in the system must be controlled by a separate thermostat so that the minimum temperature of return water can be guaranteed.
5. We recommend you to use the boiler in a system with one equalizing tank the volume of which should
be 500 - 100 l to achieve a higher service life of the pellet burner and lower fuel consumption.
CAUTION - If the boiler is equipped with Laddomat 21 or a hot-water thermo-regulation valve - 60°C and an equalizing tank (see the attached diagrams), the boiler body
is subject to an extended guarantee of 36 months instead of 24 months. The guarantee
period of the other parts remains unchanged. If these principles are not observed, the
service life of the boiler body may be considerably reduced due to low-temperature
corrosion.

Operation Manual - GB
ATMOS D14P, D21P and D25P hot-water boilers are designed for convenient heating of family
houses, holiday homes and other buildings with pellets. For the heating you can use high-quality
wooden pellets with the diameter of 6 to 8 mm. The boiler is not intended for burning of wood,
sawdust and minor wood waste.
GB
1. Application
2. Technical description
The boilers are designed in such a way that in their left or right side an ATMOS A25 pellet burner
with a conveyor is installed that is attached to a boiler frame with an 18 x 32 mm sealing cord with the
use of screws. The boiler body is made as a weldment of steel sheets with the thickness of 3-6 mm.
It consists of a combustion chamber that is equipped in its top part with a three-tube exchanger with
inserted decelerators that increase efficiency. In the bottom part of the boiler there is a large ash pan.
The front part of the boiler is equipped in its top part with a cleaning door behind which a stainlesssteel screen ensuring high quality of fuel combustion with high efficiency is inserted. The boiler
body is insulated from the outside with mineral felt located under the sheet-metal covers of the outer
boiler jacket. In the top part of the boiler there is a panel with the main switch, the automatic deashing
switch (if installed), the switch of the pellet burner, an operation (control) thermostat, a pump thermostat, a safety thermostat, a thermometer and a 6.3A fuse. In the bottom right part of the boiler there is
a blind flange for additional installation of automatic ash discharge. The boiler is not equipped with a
cooling loop against overheating as thanks to the small quantity of fuel in the burner there is no risk
of boiler overheating in case of a power supply failure.

Automatic removal of ash from the boiler body
As an accessory for every pellet boiler produced after April 1, 2010
(from the serial no. 209500 on) you can equip the boiler with automatic ash removal from the boiler body to an additional ash pan
that only needs emptying once every 3 to 45 days depending on the
quality of pellets and heating intensity. This automatic device uses
a worm conveyor with a gearbox to remove ash from the chamber
under the burner in regular intervals two times a day for one minute
or on the basis of another setting in the deashing module, which is
installed under the boiler hood. You can repeat the cycle any time by
turning off and on the switch /20(15)/ on the boiler. When the additional ash pan is completely full, the ash removal device (worm) will be automatically switched off and
the deashing module will start to emit a sound signal. You can restart the device after cleaning (emptying)
of the additional ash pan by merely turning off and on the switch /20(15)/ on the boiler for 5 seconds.
The automatic deashing system does not require any special operation; you only need to
empty the additional ash pan in regular intervals that is attached with two securing clips
with a safety pin to the boiler, which must be properly snapped during operation of the
boiler to prevent the deashing system from releasing and the ash from getting to the boiler
room. You must also properly tighten and snap the body of the automatic ash removal system and the lid of the entire additional ash pan top prevent ash from being pushed to the
boiler plant. When installing this system follow the installation instructions supplied with it.
CAUTION - The deashing system for the D14P, D21P and D25P boilers is not the same as for the
D15P and D20P boilers and is sold separately under a different code. The recommended additional
ash pans with the volume of 28 and 67 l are the same.

Operation Manual - GB
The prescribed fuel are high-quality pellets of Ø 6 - 8 mm and the length of 10 - 25 mm and
the calorific value of 16 - 19 MJ/kg-1. Such pellets are considered as high-quality pellets that do not
disintegrate into sawdust and are made of soft wood without bark and other pollutants (white pellets).
We also recommend you to burn pellets without biological additives that reduce burning-down of the
fuel and increase ash production.

7. Type of environment and location of the boiler with the
burner in the boiler room
GB
Boilers with a pellet burner may be used in the AA5/AB5 basic environment in accordance with
the ČSN3320001 standard. Boilers must be installed in a boiler room with guaranteed sufficient supply of combustion air. It is unacceptable to locate boilers on residential premises (incl. corridors). The
cross-section of the opening
for supply of combustion air
to the boiler room must be at
least 350 cm2 for boilers with
an output of 15 - 45 kW.
1. Chimney
2. Flue gas duct
3. Boiler
4. A25 burner
5. External conveyor
6. Bin (500 l)
8. Chimney
A boiler with a burner must always be connected to the chimney vent with consent of the
responsible chimney maintenance company. The chimney vent must always produce sufficient
draught and exhaust flue gas to the free atmosphere in virtually all operation conditions. For proper
function of boiler the separate chimney vent must be properly dimensioned as the combustion, output and service life of the boiler depends on its draught. The draught of a boiler directly depends
on its cross-section, height and roughness of the inner wall. No other device may be connected to the
chimney to which a boiler is connected. The diameter of the chimney must not be smaller than the
outlet on the boiler (min. 150 mm). The chimney draught must achieve prescribed values (see the
technical specifications in the boiler manual). However, the boiler must not be excessively high so as
not to reduce the efficiency of the boiler and not to disturb its combustion (tear the flame). In case of
too strong draught install a throttling flap or draught reducer in the flue gas duct between the boiler
and the chimney.
Guideline values of dimensions of the chimney cross-section:
20 x 20 cm
height 7 m
Ø 20 cm
height 8 m
15x15cm
height 11 m
Ø 16 cm
height 12 m
The exact determination of chimney dimensions is defined by the ČSN 73 4201 standard.
The prescribed chimney draught is specified in the “Technical data” chapter of the manual of the
particular boiler.
12 - GB
www.atmos.cz
Operation Manual - GB
The flue gas duct from the boiler must lead to the chimney vent. If the boiler cannot be connected
directly to the chimney vent, the corresponding flue gas duct adapter must be as short as possible with
regard to the particular conditions, but not longer than 1 m, without additional heating surface and it
must rise towards the chimney. Flue gas ducts must be mechanically strong and leak-proof for flue
gas and cleanable inside. Flue gas ducts must not lead through other owners‘ residential or commercial units. The inner
cross-section of the flue gas duct must not be larger than the
inner cross-section of the smoke uptake and must not get
narrower towards the chimney. The use of smoke elbows is
not suitable. Designs of passages of flue gas ducts through
structures of flammable materials are defined in Annexes 2
and 3 of ČSN 061008 and are mainly suitable for mobile
units, wooden huts, etc.

3 - Throttling flap (draught reducer)
INFO - In case of too strong draught of the chimney install a throttling flap /3/ or a draught
reducer in the flue gas duct, see the ATMOS price list.
10. Fire protection within the installation and use of heat appliances
Extract from ČSN 061008 - Fire safety of local appliances and sources of heat
Safe distances
On installation of an appliance the safe distance from building materials must be maintained, at least
200 mm. This distance is valid for boilers and flue gas ducts located near flammable materials of the
B, C1 and C2 flammability class (the flammability class is specified in tab. no. 1). The safety distance
(200 mm) must be doubled if boilers and flue gas ducts are located near flammable materials of the
C3 class (see tab. no.1). The safety distance must be doubled if the flammability class of flammable
material is not evidenced. The safety distance may be reduced to a half (100 mm) if you use a non-flammable heat insulating panel (asbestos panel) with the thickness of at least 5 mm, located 25 mm
from the protected flammable material (flammable insulation). A shielding panel or protective screen
(on the protected object) must exceed the outline of the boilers (incl. flue gas ducts) at each side by
at least 150 mm and the top surface of the boiler by at least 300 mm. A shielding panel or protective
screen must also be used to protect fixtures of flammable materials if the safe distance cannot be
maintained (e.g. in mobile units, huts, etc. - more details in ČSN 061008). The safety distance must
also be maintained in case of installation of fixtures near boilers.
If boilers are located on a floor of flammable materials, they must be installed on a non-flammable, heat-insulating pad, exceeding the ground plan at the side of the feeding and ashpan opening
www.atmos.cz
GB - 13
Operation Manual - GB
by at least 300 mm before the opening - at the other sides by at least 100 mm. As non-flammable, heat
insulation pads you can use all materials of the A flammability class.
GB
Tab. 1
Flammability classes of building materials and products
A - no flammability
granite, sandstone, concrete, brick, ceramic tiles, mortar, fire-resistant plastering, etc.
B - difficult flammability
Akumin, Izomin, cemented fibreboard, Lignos, panels of basalt felt,
fibreglass panels, Novodur
C1- poor flammability
hardwood (oak, beech), hardboard panels, plywood, Sirkolit, Werzalit, hardened paper (Formica, Ecrona)
C2- medium flammability
softwood (pine, larch, spruce), chipboard and cork panels, rubber
flooring (Industrial, Super)
C3- high flammability
Fibreboard panels (Hobra, Sololak, Sololit), cellulose materials,
polyurethane, polystyrene, polyethylene, lightened PVC
WARNING - In circumstances leading to the danger of transient ingress of flammable gases
or vapours and during work that might result in a temporary risk of a fire or explosion (e.g.
gluing of linoleum, PVC, etc.) the boilers must be put out of operation in time before the
occurrence of the danger. No objects of flammable substances may be put on the burner
and boiler in a smaller distance than the safe distance from them (more - see ČSN EN
13501-1).
11. Connection of boilers to the electric mains
The boilers are connected to 230 V, 50 Hz mains with a mains cable without a plug. The mains
supply cable is of the M type and in case of repair it must be replaced with the same type by the servicing organization. Boilers must be connected to the mains by a qualified person in accordance with
valid regulations of the particular country.
CAUTION - The mains cable must not be equipped with a plug (designed to be connected
to a socket). It must be connected in a fixed way to a switchboard or junction box to avoid
confusion of the conductors.

CAUTION - The installation of the boiler must always be carried out in accordance with a
prepared design. The boiler may only be installed by persons trained by the manufacturer.
14. Selection and method of connection of control and heatingsystem elements
The boilers are delivered to the user with the basic control of the boiler output, which complies with
the requirements for the heating comfort and safety. The control ensures the required output temperature of the boiler water (80-90°C). The boilers are equipped with a built-in thermostat controlling
the pump in the boiler circuit. The connection of these elements is indicated in the electric wiring diagram. Each pump in the system must be controlled with a separate thermostat to avoid cooling of the
boiler at the return line below 65°C. If the boiler is installed without a storage or equalizing tank, the
pump in the circuit of the heated building must be controlled by a separate thermostat or electronic control unit to only run when the pump in the boiler circuit is running. If you use two thermostats, either for
the control of one pump, set the thermostat that controls the pump in the circuit of the heated building
to the value of 80°C and the thermostat that controls the pump in the boiler circuit to the value of 75°C.
You can also control both the pumps with one thermostat at the same time. If there is very good spontaneous (gravity) circulation of water between the boiler and the system, which extends the time necessary for the boiler to reach the required temperature, you can reduce the setting of the thermostat of the
boiler circuit pump to a lower temperature. The required water temperature for the building is always
set with the use of a three-way mixing valve. The mixing valve may be controlled manually or with an
electronic control unit, which will contribute to more comfortable and more economical operation of
the heating system. The way of connection of all the elements is always determined by the designer
in accordance with the specific conditions of the heating system. The electric installation related to
the sufficient equipment of the boilers with the above mentioned elements must be implemented by a
qualified person in accordance with valid ČSN EN standard. If you install the ACD01 electronic control
unit, follow the instructions in the operation manual of this unit. Connect this control unit in the boiler
in accordance with the electric wiring diagram in this manual. Never switch off the ACD01 electronic
control unit outside the heating season (with the main switch on the boiler)!
16 - GB
www.atmos.cz
For the installation of the boiler we recommend you to use an open expansion vessel;
however, it may also be closed if permitted by the legislation of the particular country.
You must install the boiler in such a way to avoid its overheating and consequent damage even in case of a power supply failure.
During the installation support the back part of the boiler to raise it by 10 mm to facilitate its rinsing and bleeding.
GB
Operation Manual - GB
For the control of the heating system we recommend the following controllers:
a) ATMOS ACD 01 - equithermal control set for solid fuel boilers
b) KOMEXTHERM, Prague

15. Protection of the boiler from corrosion
The prescribed solution consists in the installation of the boiler with Laddomat 21, or a thermo-regulation valve, which allows you to create a separated boiler and heating (primary and secondary)
circuit to ensure the minimum temperature of return water to the boiler of 65°C. The higher the
return water temperature is, the lower you will keep condensation of tar and acids that are harmful for
the boiler body. The output water temperature of the boiler must be permanently in the range
of 80 - 90°C. The flue gas temperature must not drop below 110°C during normal operation. A low
flue gas temperature causes condensation of tar and acids even though the output water temperature
(80 - 90°C) and the return water temperature (65°C) is maintained. These situations may occur e.g.
in case of a wrong setting of the pellet burner (low output). For the outputs of 4 - 100 kW you can
also use a three-way mixing valve with a servo drive and electronic control to maintain the minimum
temperature of return water to the boiler (65 - 75°C).
CAUTION - We recommend you to always use the D14P, D21P and D25P boilers in
combination with an equalizing tank with the volume of 500 to 1000 l.

With its construction, Laddomat 21 replaces the traditional connection composed of individual parts.
It is composed of a cast-iron body, thermoregulatory valve, pump, non-return flap valve, ball valves
and thermometers. When the water temperature
reaches 78 °C, the thermoregulatory valve opens
the water supply from the storage tank. The connection with Laddomat 21 is considerably easier
and therefore, we recommend it. A spare thermocartridge of 72 ° C is supplied with the Laddomat
21 device. It is used for boilers over 32 kW.

WARNING - Laddomat 21 is designed only for boilers with output up to 75 kW (inclusive). We recommend using it only with boilers with output up to 50 kW (inclusive).
20. Thermoregulatory valve
Thermoregulatory valve type ESBE, TV 60 °C is used with
solid fuel boilers. When the boiler water temperature reaches
+ 60 °C , the thermoregulatory valve opens and fluid from
the building heating circuit (2) enters the boiler circuit ( 3 →
1). Inlets 1 and 3 always remain open. This ensures that the
minimum temperature of the water returning to the boiler
is maintained. If need be, a thermoregulatory valve set to a
higher temperature (E.g. 72°C) may be used.
Recommended sizes of the thermoregulatory valve TV 60°C.

21. Operation instructions
Preparation of boilers for the operation
GB
Before putting the boiler in operation you must make sure that the system is filled with water and
bled. You must always operate the boiler in accordance with the instructions contained in this manual to
achieve high quality and safety of the functionality of the boiler. The boiler may only be operated by
adult persons. The commissioning of the boiler must be done in accordance with this manual and the
operation manuals attached to the pellets burner by a qualified person.
Before igniting pellets perform several operations. Check all the lids and doors for proper closing. Check whether the burner is properly tightened to the boiler over the gasket and that the end
switch stop is in its place. Also, check the hose between the burner and the conveyor for proper tensioning and such inclination that allows free falling of pellets to the burner. They must not accumulate in
the hose. The angle of the worm conveyor should be at least 45°; otherwise the boiler may not achieve
the nominal output.
If everything is OK, draw pellets to the conveyor. In the case of the ATMOS A25 burner plug the
power supply cord of the conveyor to a standard 230V/50Hz socket. When pellets start to fall out of the
conveyor, plug the power supply cord of the conveyor back to the socket for normal operation. Turn on
the main switch (green), the switch of the pellet burner and the switch of the automatic deashing system
(if installed).
Adjust combustion of the burner with the use of a flue gas analyzer in the measurement place
(opening) in the flue between the boiler and the chimney. Always adjust the burner in a stabilized
condition, approx. 20 - 30 minutes after fuel ignition. If there is no flue gas analyzer available for the
boiler adjustment at the moment, you can adjust the pellet burner „roughly by guesswork“. Set the
quantity of fuel and combustion air in such a way to stop the flame just before the opposite wall (the
flame should not touch the wall). However, the flames must not turn at the opposite wall. In such a way
add combustion air (open the fan flap) or reduce the fuel supply.
CAUTION - This adjustment does not replace adjustment made with the use of a flue gas analyzer by a qualified person. Changes of settings of the boiler and burner may only be performed
by a person that is qualified in accordance with all the valid regulations and ČSN EN standards.
Burner flame ending 1 - 3 cm before the opposite wall.

RECOMMENDATION - We recommend you to select the container size of 500 l to 1000
l, which will be sufficient for 3 to 14 days, depending on the consumed power. The larger
the volume of the container, the better. The length of the conveyor may be 1.5 m, 2.5 m or
2.5 m. As the pellet storage you can also use a clearly delimited part of the room complying
with fire regulations from which pellets may be drawn to an intermediate storage container
at the boiler, or directly to the boiler.

GB - 21
Operation Manual - GB
24. Boiler room with a large built-in pellet storage
GB
A boiler plant with a built-in pellet storage with the volume of
e.g. 5 m3 in which you can store
3250 kg of pellets. For this purpose
a 2 m (2.5 m) conveyor is used. For
easy access to the storage a segmented opening is produced that can
be adapted to the pellet level in the
storage and enables cleaning of the
storage from dust and dirt once a
year. In the top part of the storage
there are two openings for replenishment of pellets from a cistern that
have different sizes with regard to
pellet suppliers.
For optimum collapsing of the pellet heap the optimum angle of the
inner walls in the storage must be
at least 45°. All the walls are inclined to the lowest point of the storage from which the worm conveyor
draws pellets.
CAUTION - If pellets are drawn to the storage in the boiler plant directly from the cistern,
several principles must be observed that prevent their crushing during pneumatic transport.
First of all you must make sure that they do not hit the hard wall of the storage, but a screen
that is suspended in the centre of the storage from the ceiling. This way you will ensure even
filling of the storage and prevent crushing into small pellets and dust. Ask the pellet suppliers
about further possibilities and conditions of pellet drawing.
22 - GB
www.atmos.cz
Operation Manual - GB
The burner and the boiler must be cleaned regularly and thoroughly once every 1 to 30 days depending on the quality of pellets and the output setting. Fly-ash and dirt accumulated in the combustion
chamber of the burner and boiler considerably reduce the service life and output. Do the regular cleaning of the boiler in such a way that you first let the burner burn out (turn off the burner switch /20/).
Open the cleaning door, remove the front stainless-steel screen and clean the combustion chamber of
the burner, incl. the air openings in the chamber with the provided poker. If the combustion chamber of
the burner is heavily soiled, remove it for cleaning. Further, remove the decelerators from the tube plates
located in the top part of the combustion chamber and clean them with the provided brush. During this
cleaning return the front stainless-steel screen back to the boiler, but the other way round to make it
prevent large quantities of dust from falling out of the boiler during the cleaning. Also, do not forget
to clean the back smoke channel and scrape the walls of the combustion chamber of the boiler with the
provided poker or brush. Finally, remove the ash pan and dispose of the ash while observing all the fire
measures. The interval of the cleaning and ash removal depends on the fuel quality, heating intensity,
chimney draught and other circumstances. Put everything in the original condition after the cleaning.
At least once a year remove the burner and clean it completely. See the manual of the burner.

Operation Manual - GB
26. Maintenance of the heating system, including boilers
GB
At least once every 2 weeks check or replenish water in the heating system. If the boilers are out
of operation in winter, there is a danger of water freezing in the system and therefore you had better
drain water from the system or fill it with an antifreeze mixture. Otherwise, only drain water in inevitable cases and for the shortest possible time. After the end of the heating season thoroughly clean
the boiler and replace the damaged parts. Do not wait with the replacement of parts until the last
moment; prepare the boiler for the heating system in spring already.
27. Operation and supervision
Boiler operators must always follow the operation and maintenance instructions. Interventions
into boilers that could endanger the health of the operators or other persons in the vicinity are prohibited. Boilers may only be operated by a person that is more than 18 years old, that has been acquainted
with the instructions and operation of the equipment and that complies with the requirements of § 14
of the Directive no. 24/1984 Coll. You must never leave unattended children near boilers that are in
operation. During the operation of solid fuel boilers it is prohibited to use any flammable liquids for
lighting the fire and it is also prohibited to increase the nominal output of the boiler during operation
(overheating). You must not put flammable objects on the boiler and near the fuel feeding and
ash pan openings and ash must be stored in non-flammable containers with a lid. Boilers in
operation must be under occasional supervision of the operator. The user may only carry out repair
consisting in simple replacement of a spare part (e.g. a sealing cord, etc.). During the operation check
the doors and cleaning openings for tightness and always tighten them properly. The user must not alter the structure and electric installation of boilers. The boiler must always be cleaned properly and in
time so that free passage of all the ways can be guaranteed. Cleaning doors must always be properly
closed.

Replacing the door sealing cord
Procedure: Use a screwdriver to remove the old cord and clean the groove where it was seated.
Use a hammer to slightly shape the cord from the square cross-section to the trapezoidal cross-section. Grip the cord and impress it along the perimeter of the door (with the narrower base to the groove)
www.atmos.cz
GB - 25
Operation Manual - GB
to make it sit in the groove (you can use a small hammer as an auxiliary tool). Hold the handle of the
door closure pointing upwards and by means of slow knocks with the door press the cord into the
groove until you can close the door. Finally, adjust the position of the wheel where the cam of the
closure gets engaged. Only using this procedure you can guarantee tightness of the door!
GB
Adjusting the door hinges and closures
Cleaning doors are firmly connected to the boiler body with a set of two hinges. A hinge consists
of a nut that is welded to the boiler body and an adjustment crew to which the door is fixed with a
pin. If you want to change the setting of the hinges, first release and lift the top hood (control panel),
knock both the pins out, remove the door and turn the adjusting screw (hinge) with the right thread as
necessary. Put everything in the original condition in the reverse order.
The door closure consists of a lever with a handle and a cam that engages to a wheel that is screwed to the boiler and secured with a nut preventing its turning. After a certain time the sealing cord in
the door gets compressed and therefore the wheel should be screwed deeper into the boiler. So release
the nut on the wheel and screw it into the boiler in such a way that the handle can indicate 20 minutes
on an imaginary clock dial after firm closing of the door. Finally, tighten the nut.
30. Environment protection
ATMOS gasification boilers comply with the most stringent environmental requirements. The
boilers are certified in accordance with the EN 303-5 European Standard and belong to class 3.
Disposal of the boiler after the end of its service life
You must ensure ENVIRONMENT-FRIENDLY disposal of individual parts of the boiler.
Properly remove fly-ash from the boiler before its disposal and put it in a dustbin.
Scrap the boiler body and the hoods.
Ceramic parts and insulation - discard to a legal dumping site.
NOTE - To ensure environment-friendly heating you must not burn any other fuel or substances in the boiler than specified. This is mainly the case of plastic bags, various types of
plastic materials, paint, textiles, glass fibre as well as sawdust, sludge, vegetable (biological)
pellets, dust coal.
